A source said the designer feels like she needs to "tap into a younger generation", so she'll ring the songstress for a "mood call" and "asks her to explain what has influenced her mood that day - colors, textures, patterns."

Oh. So it's like phone sex for fashion?!

We imagine they go like this:

Stella: RiRi, darling! Where have you been?RiRi: In London.Stella: Fancy! And what are you wearing?RiRi: You.

Okay, maybe they don’t go exactly like that, but we can pretend!

Now it's time to speculate about these moody calls.

Could the two be in cahoots for capsule collection soon?! Or maybe we can expect to see lots of Rihanna look-a-likes on Stella's catwalk during fashion week?
